Abstract
Conventional semen parameters have long been considered fundamental in male fertility analyses. However, doubts have been raised regarding the clinical utility of the assessment of spermatozoa (sperm) DNA damage. In this retrospective study, we investigated the potential correlation between conventional semen parameters and semen DNA fragmentation (SDF) assessed as sperm DNA damage, in 11,339 semen samples collected between January 2019 and June 2022. We observed significant negative correlations between the DNA fragmentation index (DFI) and sperm viability (correlation coefficient [r] = -0.514) as well as progressive sperm motility (r = -0.512, p < 0.05). Samples were categorized into three groups according to DFI levels (Groups A, B, and C: ≤15%, 15 < DFI ≤30%, and >30%, respectively). Furthermore, the percentage of semen samples with normal sperm conventional parameters in Groups A, B, and C was 76.7% (4369/5697), 61.4% (2351/3827), and 39.7% (721/1815), respectively. Moreover, according to the reference values of conventional sperm parameters, the samples were divided into Groups F, G, and H with all normal, only one abnormal, and > two abnormal parameters, respectively. In addition, the proportions of samples with abnormal DFI values (>30) in Groups F, G, and H were 9.7% (721/7441), 23.1% (618/2676), and 39.0% (476/1222), respectively. Multivariate logistic regression models demonstrated that sperm vitality, progressive sperm motility, normal sperm form, total sperm count, semen volume, age, and some sperm kinematics collectively improved the area under the receiver operating characteristic curve (AUROC) to 0.861, surpassing the predictive value of a single predictor of pathologically damaged sperm DNA. Our study suggests that samples with abnormal sperm parameters may have a higher likelihood of high DNA fragmentation. Furthermore, certain semen parameters could be potential indicators of sperm DNA fragmentation, aiding sperm selection in assisted reproductive procedures.

Abstract
Advancements in the management of patients with chronic myeloid leukemia (CML) allowed them to achieve survival comparable with their healthy counterparts. Consequently, their care has widened with growing focus on quality of life, including parenting children. Although tyrosine kinase inhibitors (TKI) are contraindicated in pregnancy given their teratogenic effect, their effect on male fertility is less clear with contradictory results from animal studies and case reports/series. We compared the sperm analysis parameters, as the gold-standard assessment for male fertility, of 11 patients with CP- CML before and after TKI therapy. Median therapy duration was 5.1 years (range: 2.5-16.5). The sperm concentration, % progressive, and total motility before and after therapy were not significantly different (p = 0.376, 0.569, and 0.595, respectively). Our results suggest no impairment in fertility potential in male patients after TKI therapy. A larger sample size is crucial to support/refute our findings.

Abstract
BACKGROUND Fertility declines with increasing age and physicians often delay childbearing beyond prime reproductive years for the sake of medical training. However, the risks of infertility in male physicians compared to the general population remain poorly studied. OBJECTIVES To characterize rates of infertility among male physicians and identify barriers in access to fertility care and family building. MATERIALS & METHODS Between June 2022 and December 2022, male physicians were invited to complete a questionnaire regarding fertility and family building. Surveys were disseminated electronically via social media and professional medical societies using Qualtrics (Provo, UT). RESULTS Two hundred thirty-five responses were included in the final analysis. The mean age of respondents was 36.3 ± 7.4 years. Of 151 respondents with children or currently attempting to have children, 66 (43.7%) delayed family building due to their medical training or career. The most influential factors affecting timing of children were lack of flexibility in schedule, lack of time, stress, and financial strain. Forty-three (18.3.%) respondents had seen a doctor for fertility evaluation; an additional 12 (5.1%) said they considered doing so but did not, mostly due to being too busy. Sixty (25.5%) had undergone semen testing in the past. Thirty-one (13.2%) reported a diagnosis of fertility issues in either themselves or their partner. Twenty-seven (11.5%) endorsed either them or their partner having undergone assistive reproductive technologies or other procedures for infertility. DISCUSSION A significant proportion of male physicians delayed building their family or seeking fertility evaluation due to their medical career. Around 23.4% of male physicians have either seen or considered seeing a physician for fertility evaluation, suggesting a high prevalence of infertility in this cohort. CONCLUSION Our results indicate a need for interventions to support family building and fertility evaluation and treatment among male physicians.

Abstract
(1) Background: Standard semen analysis methods may exhibit variability between observers and/or human error; therefore, additional methods are needed to overcome these handicaps. We aimed to present a new smartphone-applied semen analyzer, Sperm Cell™, investigate its diagnostic efficacy by comparing it with the standard analysis method, and determine its user-friendly nature. (2) Methods: A cross-sectional study was conducted on a large sample cohort, including 102 men. Three semen analyses were performed for each semen sample. The first employed the standard manual method, whereas the others were smartphone-based analyses performed by technicians and patients. We compared major semen parameters between the three semen analyses. The user-friendly nature of the analyzer was also evaluated with a mini-questionnaire completed by the participants. (3) Results: The determined median sperm count, motile sperm count, and percentage of motile sperms, on standard manual semen analysis, were 50.00 × 106/mL (0-160 × 106/mL), 23.94 × 106/mL (0-108 × 106/mL) and 50.00% (0-73.00%), respectively. Median sperm count and motile sperm count were 50.52 × 106/mL (<1-150 × 106/mL) vs. 55.77 × 106/mL (<1-160 × 106/mL) and 23.34 × 106/mL (0-105 × 106/mL) vs. 23.53 × 106/mL (0-104 × 106/mL) for SpermCell™-based semen analysis performed by a technician and patients themselves, respectively. The percentages of motile sperms were 47.40% (0-67.00%) vs. 47.61% (0-80.20%), respectively. All the parameters were statistically similar between the three semen analysis methods (p > 0.05 for each). The SpermCell™ analysis results were correlated with the standard manual method with up to 0.85 correlation coefficients. Moreover, substantial diagnostic accuracy, sensitivity and specificity were obtained in determining the oligospermia and asthenozoospermia via the device-based analyses performed by technician and patients. The mini-questionnaire results revealed that the analyzer is useful. (4) Conclusions: The novel smartphone-applied semen analyzer is a helpful tool with acceptable diagnostic accuracy in determining the major semen parameters. It can be used as an efficient at-home point-of-care testing method in the initial assessment of couples with infertility concerns.

Abstract
OBJECTIVE Sperm Associated Antigen 11A (SPAG11A) protein is a family of the epididymis-specific secretory proteins implicated in sperm maturation and function. Varicocele might cause pathophysiological difficulties in the testis and epididymis, with a harmful effect on the environment for spermatogenesis and sperm maturation. The aim of this study was to evaluate the expression level of the SPAG11A gene and sperm parameters in infertile men with grade 1 and 2 varicocele before and after treatment. METHODS Semen specimens were collected from 20 infertile men with varicocele pre-and post-treatment and 10 healthy volunteers. Semen analysis was conducted according to world health organization guidelines. Real time PCR (qRT-PCR) reaction was applied for determination of SPAG11A mRNA expression. RESULTS The results showed that there was a significant difference between the concentration and normal morphology between pre- and post-treatment groups and the controls. There were significant differences between pre-treatment and control groups in terms of progressive and non-progressive mobility. SPAG11A mRNA levels were significantly lower in the pre-treatment group than in healthy control subjects (p=0.007). There was no statistically significant difference in the expression of SPAG11A as well as semen parameters in the post-treatment group compared to the pre-treatment group. CONCLUSIONS SPAG11A gene expression and semen parameters may be affected by varicocele. Whether varicocele treatment is an effective approach to reduce the adverse effect of this disease on SPAG11A expression and semen parameters needs further investigation.

Abstract
BACKGROUND Socioeconomic differences are present within the population of men who experience infertility and seek treatment. OBJECTIVE To study the association of socioeconomic status with semen parameters in a group of men using mail-in semen analyses. MATERIALS AND METHODS The records of 11,134 men that used mail-in semen analyses from a fertility company were identified. Their demographic information, semen parameters, and ZIP codes were collected. Area deprivation index (ADI) was used as a proxy for socioeconomic status and was calculated for each individual using their ZIP codes in order to measure their level of socioeconomic deprivation. A higher ADI signifies a more deprived area. The association between ADI and the semen parameters of this group was measured using linear regression analysis adjusted for age. RESULTS 11,134 men were included in the study with a median age of 35 years (interquartile range (IQR): 32-40) and a median ADI of 83 (IQR: 68-97). The cohort had a median sperm concentration of 31 million/mL (IQR: 14-59), median total sperm count of 123 million (IQR: 57-224), median total motile sperm of 35 million (IQR: 9-95), median total motility of 32% (IQR: 15-52), progressive motility of 22% (IQR: 9-38), and morphology percent normal of 4% (IQR: 2-7). Higher ADI, indicating lower socioeconomic status, was negatively associated with various semen parameters, including sperm concentration, total sperm count, total motile sperm, and total and progressive motility. DISCUSSION AND CONCLUSION Men who live in more deprived areas are more likely to have worse semen parameters. Further research is needed to thoroughly examine the impact of socioeconomic status on male fertility. A comprehensive approach that targets upstream social, economic, and healthcare factors can possibly alleviate the negative association of socioeconomic status with fertility and semen parameters.

Abstract
Background Male infertility is one of the major reproductive health concerns, causing a lot of distress for couples globally. Others have looked into its connection to vitamin D deficiency, but their findings are conflicting. Aim This study aimed to determine the relationship between male infertility and vitamin D deficiency among Nigerians. Method This analytical cross-sectional study was conducted among 132 men. A purposive sampling technique was employed to recruit 66 participants in the study (men with infertility) and control groups (men with proven fertility). Descriptive statistics were conducted, while the association between vitamin D level and sperm parameters was assessed using bivariate and regression modeling. A two-tailed test of the hypothesis was assumed, and the level of statistical significance was set at a P-value < 0.05. Results None of the participants had a serum vitamin D deficiency. However, the overall serum vitamin D insufficiency rate was 15%. The median vitamin D level for the total study population (both fertile and infertile) was 37.52 ng/ml (IQR: 32.1 - 51.69). This study demonstrated no association between serum vitamin D levels and male infertility, as well as no association between serum vitamin D levels and the quality of semen parameters. Conclusion There was no significant association between vitamin D levels, male infertility, and seminal fluid parameters. However, larger multi-center studies are recommended to provide further insights into this conclusion.

Abstract
The well-documented relationship between chronological age and the sperm methylome has allowed for the construction of epigenetic clocks that estimate the biological age of sperm based on DNA methylation, which we previously termed sperm epigenetic age (SEA). Our lab demonstrated that SEA is positively associated with the time taken to achieve pregnancy; however, its relationship with semen parameters is unknown. A total of 379 men from the Longitudinal Investigation of Fertility and Environment (LIFE) study, a non-clinical cohort, and 192 men seeking fertility treatment from the Sperm Environmental Epigenetics and Development Study (SEEDS) were included in the study. Semen analyses were conducted for both cohorts, and SEA was previously generated using a machine learning algorithm and DNA methylation array data. Association analyses were conducted via multivariable linear regression models adjusting for BMI and smoking status. We found that SEA was not associated with standard semen characteristics in SEEDS and LIFE cohorts. However, SEA was significantly associated with higher sperm head length and perimeter, the presence of pyriform and tapered sperm, and lower sperm elongation factor in the LIFE study (p < 0.05). Based on our results, SEA is mostly associated with defects in sperm head morphological factors that are less commonly evaluated during male infertility assessments. SEA shows promise to be an independent biomarker of sperm quality to assess male fecundity.

Abstract
INTRODUCTION We aimed to assess the sexual and the reproductive functions in males post COVID-19 infection in Beni-Suef Governorate. METHODS One hundred men were recruited in the current study. All participants were assessed by the Arabic validated version of the International Index of the Erectile Function 5 (ArIIEF-5), semen analysis, and Hospital Depression and Anxiety Scale (HADS). Finally, morning testosterone serum level was measured. RESULTS There were significant decreases in the sperm total motility, the ArIIEF-5 score, and serum total testosterone in the post COVID-19 patients after 3 months when compared to the controls. However, there were significant increases in the sperm total motility, the ArIIEF-5 score, and serum total testosterone in the post COVID-19 patients after 6 months group when compared to the post COVID-19 patients after 3 months group. Moreover, there was a significant increase in the HADS score in the post COVID-19 patients after 3 months when compared to the controls. In contrast, there was a significant decrease in the HADS score in the post COVID-19 patients after 6 months when compared to the post COVID-19 patients after 3 months. CONCLUSION Our study had shown temporary impairment of sexual and reproductive functions in post COVID-19 convalescent males especially after 6 months from the onset of the infection.

Abstract
Background Post-vasectomy semen analysis (PVSA) completion rates after vasectomy are poor, and minimizing the need for an additional in-person visit may improve compliance. We hypothesized that providing PVSA specimen cup at time of vasectomy instead of at a postoperative appointment might be associated with higher PVSA completion rates. Methods We performed a retrospective cohort study with historical control using medical records of all patients seen by a single provider for vasectomy consultation between October 2016 and June 2022. All patients who underwent vasectomy were included. Patients who underwent vasectomy prior to 05/01/2020 had PVSA specimen cup given at postoperative appointment two weeks following vasectomy, and those who underwent vasectomy after 05/01/2020 were given PVSA specimen cup at time of vasectomy. PVSA completion, demographic, and clinical outcomes data were collected. Logistic regressions were used to investigate associations between PVSA completion rates and timing of PVSA specimen cup provision. Results There were no significant differences among study cohorts across all patient demographics analyzed, including age, body mass index (BMI), age of primary partner, presence of children, and history of prior genitourinary infection. A total of 491 patients were seen for vasectomy consultation between October 2016 and June 2022; among these patients, 370 underwent vasectomy. Of these, 173 (46.8%) patients underwent vasectomy prior to 05/01/2020 and were given PVSA specimen cup at postoperative visit; 197 (53.2%) patients underwent vasectomy after 05/01/2020 and were given PVSA specimen cup at vasectomy. Providing PVSA specimen cup at time of vasectomy was associated with higher odds of PVSA completion than providing PVSA specimen cup at postoperative visit [62.4% vs. 49.7%; odds ratio (OR) =1.68; 95% confidence interval (CI): 1.11, 2.55]. Adjusting for all identified confounders excludes 35 (9.5%) patients without a primary partner and shows no statistically significant association in cup timing [adjusted OR (aOR) =1.53; 95% CI: 0.98, 2.39]. Adjusting for all identified confounders except age of primary partner revealed timing of specimen cup provision at time of vasectomy was associated with higher odds of PVSA completion (aOR =1.64; 95% CI: 1.08, 2.52). Conclusions PVSA specimen cup provision at time of vasectomy versus at postoperative appointment is associated with higher rates of PVSA completion in this retrospective cohort study.

Abstract
The underlying reasons for male-factor infertility are often unknown. 30% of all men have unexplained semen analysis abnormalities. Moreover, 15%-40% of infertile men have normal semen analyses. There have been increasing efforts to identify causes and associations that may explain idiopathic male-factor infertility. Telomeres have become an area of considerable interest in the field because of the essential roles they have in cellular division and genome integrity. Research to date most consistently supports that men with infertility have shorter sperm telomere length (STL); however, associations between shorter STL and meaningful reproductive health outcomes are less consistent. There is a major need for additional studies to better identify the role of STL in male reproductive health and use the information to improve the counseling and treatment of couples with idiopathic male-factor infertility.

Abstract
Couples trying to conceive or providing samples for Assisted Reproductive Technologies (ART) are advised against the use of lubricant-gels due to the risk of sperm-toxicity. However, gels now exist which are specifically formulated to help couples conceive but without consensus on their toxicity relative to non-specialist products. This study tested gels recently introduced as 'sperm friendly' (FertilSafe Plus, Fertile Check) alongside established lubricants intended for pleasure only using a recently published toxicity testing regime. Computer Assisted Sperm Analysis (CASA) was performed at 1 and 2 h on donor sperm (n = 12) pre-incubated with each gel (10% v/v) and controls. All gels led to a significant loss of motility/velocity at 1 and 2 h (p < 0.01), with the most significant loss from the 2 Durex pleasure products (11% and 15%, vs 47% progression) at 60 min, although these performed better than saliva (used as negative control). Incubation with FertilSafePlus led to the smallest loss of motility (24% vs 47%) at 1 h. Saliva and products designed for lubrication only exhibited the most negative effect on motility and those marketed as 'sperm safe' could be considered the best performers. Whether these affects are due to direct toxicity or are indirect due to other factors such as viscosity, pH or osmolality remains uncertain.

Abstract
BACKGROUND Human papillomavirus (HPV) infection is one of the most prevalent sexually transmitted infections that can lead to malignant pathologies as well as fertility problems. The aim of this study was to evaluate the prevalence of HPV infection in males, its impact on semen parameters, and reproductive consequences. We also evaluated potential measures that could prevent negative outcomes of HPV infection in males. METHODS A systematic literature search using PubMed/Medline and Embase databases was performed to search for English articles published until July 2023. We explored three different aspects: (1) prevalence of HPV semen infection and its impact on seminal parameters; (2) the relationship between HPV semen infection and infertility risk and reproductive outcomes; and (3) potential measures that could prevent the negative outcomes related to HPV seminal infection. The identified studies were first screened and assessed independently by one author, and then validated by two additional authors. Data were extracted from 19 studies. RESULTS The prevalence of seminal HPV infection was higher among infertile males. In addition to controversies about the real interference of seminal HPV infection on sperm parameters, a growing number of studies have demonstrated a correlation between unexplained infertility and seminal HPV infection. Semen HPV infection is also associated with lower rates of pregnancy and higher rates of miscarriage. Prevention measures such as HPV vaccination seem promising. CONCLUSION Further studies are required to confirm not only the association between HPV infection and reproductive outcomes but also the benefit of preventive measures.

Abstract
STUDY QUESTION How do the types and frequency of chromosome aberrations in couples in central China affect fertility and ART treatment? SUMMARY ANSWER Men with chromosome aberrations or polymorphisms have an increased risk of semen quality impairment and infertility, and couples affected by reciprocal translocations had a lower pregnancy rate compared with other chromosome aberrations. WHAT IS KNOWN ALREADY Karyotyping is crucial for patients affected by infertility as chromosome aberrations play an important role in the etiology of male infertility. However, the influence of chromosome aberrations and polymorphisms on sperm motility and morphology remains controversial. Data on ART treatment outcomes in infertile couples affected by chromosome aberrations are insufficient. STUDY DESIGN, SIZE, DURATION We conducted a retrospective study involving 17 054 patients affected by infertility who underwent karyotyping in our center between January 2020 and May 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS Karyotyping was performed on 17 054 patients with reproductive failure. All patients were from the central regions of China. The following data were collected from a medical records system using patient identification numbers: couples' ages, history of pregnancy and childbirth, type of infertility, years of infertility, cause of infertility, chromosome karyotypes, semen analysis results, assisted reproductive techniques performed, and treatment outcomes of ART. MAIN RESULTS AND THE ROLE OF CHANCE The incidence of chromosome aberrations was 2.04%; 2.49% in men and 1.57% in women. By analyzing the relationships between chromosome aberrations/polymorphisms and abnormal semen parameters, we found that there were significantly higher rates of asthenozoospermia, oligospermia, and teratozoospermia among men with Robertsonian translocations and sex chromosomal structural aberrations compared with those with normal karyotypes. Higher rates of asthenozoospermia and teratozoospermia were also observed among men with autosomal reciprocal translocations. The incidence of chromosome aberrations in azoospermic men (13.75%), and in men with cryptozoospermia or severe oligospermia (6.97%) was significantly higher than that in men with mild oligospermia or normospermia (0.88-2.12%). In addition, we found that the progressive movement of sperm is impaired in men with Chromosome 21 polymorphisms compared with men with normal karyotypes (39.46% ± 20.51% vs 48.61% ± 18.76%, P = 0.026). The percentage of morphologically normal forms was lower in the chromosomal polymorphism group than in the normal karyotype group (5.01% ± 2.41% vs 5.59% ± 2.14%, P = 0.001), especially in men with polymorphisms on Chromosome 9 (enlarged Chromosome 9 heterochromatin [9qh+]: 4.48% ± 2.22% vs 5.59% ± 2.14%, P = 0.006; pericentric inversion of Chromosome 9 [inv(9)]: 5.09% ± 3.11% vs 5.59% ± 2.14%, P = 0.008). ART treatment was successful in 36.00% of couples affected by chromosome aberrations. However, couples affected by reciprocal translocations achieved a lower pregnancy rate (24.07%), which may be due to the lower euploidy rates (27.31%) when compared with that in other chromosome aberrations. LIMITATIONS, REASONS FOR CAUTION First, although the initial cohort was large, chromosome aberrations were identified in a small number of patients. Second, the observational nature of the study design is limiting. Third, the couples affected by infertility in this study were all outpatients that did not undergo identical comprehensive examinations except for karyotyping, leading to the incomplete collection of medical records. Also, the population included in this study mainly focused on couples affected by infertility, which may not be included in the European Association of Urology (EAU) recommendation on male infertility. WIDER IMPLICATIONS OF THE FINDINGS Men with chromosome aberrations or polymorphisms have an increased risk of semen quality impairment and infertility. Constitutional chromosome analysis is recommended for men affected by infertility and severe oligospermia or azoospermia to facilitate early and appropriate guidance for the most suitable treatment. Carriers of chromosome aberrations can achieve acceptable pregnancy outcomes through IVF. However, couples affected by reciprocal translocations have lower pregnancy rates, and more treatment cycles are needed before a successful pregnancy. A possible explanation may be the fewer euploid embryos obtained.

Abstract
Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease affecting patients of reproductive age. Although HS shares risk factors with male infertility, only 1 epidemiological study has evaluated this association. To further evaluate this potential association, findings on semen and hormonal analysis, testicular ultrasound, and the International Index of Erectile Function (IIEF-15) were compared between 28 men attending a tertiary HS clinic during the period April 2019 to April 2021, and 44 healthy controls, spouses of infertile women undergoing semen evaluation before in vitro fertilization. Patients with HS were divided based on the absence or presence of gluteal and genital lesions. Patients with HS were younger than controls (median 27 vs 34 years, p < 0.0004) and had a higher proportion of smokers (86% vs 33%, p < 0.0001). Semen parameters in patients with gluteal-genital lesions, specifically those with severe scrotal involvement necessitating surgery, were lower than the WHO reference values and significantly lower than in patients without gluteal-genital lesions and controls. Erectile dysfunction was reported by 93% of patients with HS. These findings suggest that spermatogenesis and sexual function may be impaired in young men with HS. Therefore, multidisciplinary management of HS should include their evaluation to identify patients who might benefit from semen cryopreservation and sexual treatment.

Abstract
BACKGROUND Our aim was to evaluate the effect of COVID-19 infection on male fertility and sexual function. METHODS Thirty-one patients were investigated over a mean follow-up of 90 days (22-527) after a COVID-19 infection. Erectile dysfunction (ED), blood tests for sexual hormones, semen analysis including analysis of oxidative stress (OS), as well as COVID-19 antibody titer and the nasal COVID-19 PCR test were evaluated pre- and post-infection. RESULTS Five patients reported a mild de novo ED (16.13%). One patient had a de novo positive mixed antiglobulin reaction test after the infection. We found no significant difference between pre-COVID-19 and post-COVID-19 spermiogram parameters (p = 0.815). OS showed no significant association with COVID-19 infection, but with pathological spermiogram categories, sperm concentration, total sperm count, testis volume, FSH and testosterone. CONCLUSION COVID-19 infection does not appear to affect sperm quality and OS negatively in the intermediate term. Further investigations will be needed to assess the potential long-term effects of the infection and vaccination on male sexual function and fertility.

Abstract
Intracytoplasmic sperm injection (ICSI) using surgically retrieved spermatozoa outside the classic context of azoospermia has been increasingly used to overcome infertility. The primary indications include high levels of sperm DNA damage in ejaculated spermatozoa and severe oligozoospermia or cryptozoospermia, particularly in couples with ICSI failure for no apparent reason. Current evidence suggests that surgically retrieved spermatozoa for ICSI in the above context improves outcomes, mainly concerning pregnancy and miscarriage rates. The reasons are not fully understood but may be related to the lower levels of DNA damage in spermatozoa retrieved from the testis compared with ejaculated counterparts. These findings are consistent with the notion that excessive sperm DNA damage can be a limiting factor responsible for the failure to conceive. Using testicular in preference of low-quality ejaculated spermatozoa bypasses post-testicular sperm DNA damage caused primarily by oxidative stress, thus increasing the likelihood of oocyte fertilization by genomically intact spermatozoa. Despite the overall favorable results, data remain limited, and mainly concern males with confirmed sperm DNA damage in the ejaculate. Additionally, information regarding the health of ICSI offspring resulting from the use of surgically retrieved spermatoa of non-azoospermic males is still lacking. Efforts should be made to improve the male partner's reproductive health for safer ICSI utilization. A comprehensive andrological evaluation aiming to identify and treat the underlying male infertility factor contributing to sperm DNA damage is essential for achieving this goal.

Abstract
BACKGROUND Recurrent pregnancy loss and unexplained infertility are the current indications to test sperm DNA fragmentation according to the European Association of Urology Guidelines on sexual and reproductive health. OBJECTIVE To identify a novel and better performing model to diagnose primary infertile men presenting with altered sperm DNA fragmentation and to outline its predictive ability in respect to current European Association of Urology Guidelines' recommendations. MATERIALS AND METHODS Data from the latest 515 consecutive primary infertile men as for World Health Organization criteria were analyzed. Semen analysis, sperm DNA fragmentation (according to sperm chromatin structure assay), and serum hormones were considered in every patient. Altered sperm DNA fragmentation was defined with levels greater than 30%. Descriptive statistics was applied to compare patients with normal versus SDF > 30%. The new predicting model was identified through logistic regression analysis exploring potential predictors of SDF > 30% at first clinical presentation. Diagnostic accuracy between the two predictive models (European Association of Urology Guidelines vs. new) was assessed, and decision curve analyses tested their clinical benefit. RESULTS Of 515, 268 (51.9%) patients had SDF > 30% at clinical presentation. Patients with SDF > 30% were older (median [interquartile range] 39 [35-43] vs. 37 [34-41] years), had lower mean testicular volume (Prader 15 [12-20] vs. 17.5 [13.5-20] and lower total motile sperm count (1.80 [0.7-13.2] vs. 11.82 [4.2-44.5] × 106 ), all p < 0.001. No other clinical differences were depicted. The two groups showed similar rates of history of recurrent pregnancy loss and unexplained infertility. At multivariable logistic regression analysis, age more than 38 years (odds ratio: 2.43) and baseline total motile sperm count less than 20 × 106 (odds ratio: 3.72) were associated with SDF > 30%, after adjusting for Prader < 15, history of miscarriages and unexplained infertility, all p < 0.0001. The newly identified model (unexplained infertility + history of poli-abortions + Prader < 15 + age ≥38 years + total motile sperm count <20 × 106 ) showed higher accuracy to identify SDF > 30% at baseline in respect to European Association of Urology Guidelines (area under the curve: 72.1 vs. 52.7), with superior clinical net benefit use. CONCLUSIONS The application of the European Association of Urology sexual and reproductive health guidelines does not ensure proper identification of primary infertile men with pathological sperm DNA fragmentation. We propose a novel and better performing predictive model to identify the infertile men with altered sperm DNA fragmentation at first clinical assessment. DISCUSSION As altered sperm DNA fragmentation has been widely linked with the inability to conceive, this second-level test could be further implemented over the diagnostic workup of a broader subset of patients presenting for male factor infertility. We propose a better performing model to identify this specific category of patients.

Abstract
Introduction Although studies have shown that bariatric surgery can have a positive effect on the patient's sexual function, there are still disagreements and contradictions in this regard. The present study is aimed to evaluate semen parameters, hormonal changes of FSH, LH, testosterone, and libido following bariatric surgery. Methods The present research as a prospective study was performed on 20 male candidates for bariatric surgery referred to Golestan and Aria hospitals in Ahvaz in 2021. Semen parameters (volume, count, motility, and the percentage of sperm with normal morphology), hormonal profile (including FSH, LH test hormones), and sexual function were evaluated using the International Index of Erectile Function (IIEF-5) questionnaire before and 6 months after the surgery. Results The results of this study indicated that semen parameters did not change significantly 6 months after surgery in comparison with before the surgery (P < 0.05). After the operation, just the total level of testosterone increased significantly (2.23 nmol/L vs. 2.74, P = 0.009). However, LH and FSH levels did not change significantly six months after surgery (P = 0.858 and P = 0.287). The results indicated significant improvement in IIEF score after the operation (P = 0.011). Conclusion The findings of the present study indicated that the decrement of weight as a result of bariatric surgery had a favorable effect on the levels of serum testosterone and sexual performance, while semen parameters did not improve after surgery.

Abstract
Background The use of probiotics in the treatment of infertility is a new area of research. In this study, our objective was to examine the efficacy of probiotic supplementation on semen parameters following varicocelectomy. Materials and Methods We included infertile men in our study who were the candidates for subinguinal microscopic varicocelectomy. After the surgical procedure, the patients were randomly assigned into two groups: 38 individuals received probiotic supplementation (FamiLact®), while 40 individuals received a placebo for 3 months. We compared the preoperative semen parameters with the postoperative parameters to evaluate the effects of probiotic supplementation. Results A total of 78 patients were included in the study. The two groups were similar in terms of age, body mass index, infertility period, and semen parameters at baseline (P > 0.05). A statistically significant difference was found in sperm concentration (33.7 ± 22.5 vs. 21.1 ± 16.1 × 106/mL, P = 0.046), and the percentage of sperms with normal morphology (15.0 ± 8.9 vs. 12.0 ± 11.5, P = 0.016) at 3 months favoring the probiotic group. Although the probiotic group exhibited higher values for semen volume and sperm motility at 3 months, the differences were not statistically significant (P = 0.897 and P = 0.177, respectively). Conclusion Our study demonstrates that the short-term use of probiotics after varicocelectomy can provide additional benefits in improving semen parameters. Probiotic supplements are cost-effective and well tolerated, making them a suitable option for enhancing the outcomes of varicocelectomy.

Abstract
Background Since the association between dietary quality scores and semen quality remains unclear, we carried out a hospital-based cross-sectional study to investigate the association of Dietary Total Antioxidant Capacity (dTAC), Dietary Inflammatory Index (DII), and Alternative Healthy Eating Index (AHEI) scores with semen quality in men seeking infertility treatment. Methods This study enrolled 210 men with unexplained or idiopathic infertility. Semen samples were collected and analyzed according to the WHO 2010 criteria. Dietary data was collected using a 168-item semi-quantitative food frequency questionnaire (FFQ) developed for Tehran Lipid and Glucose Study. Multivariable logistic regression models were used to estimate the relationship between dTAC, AHEI, and DII scores with abnormal semen in crude and adjusted models. Results There were no significant differences across quartile categories of the dTAC, AHEI, and DII scores regarding semen parameters. There was a trend toward a significant direct association between DII and abnormal semen risk (p = 0.01). Infertile men in the highest quartile of DII had a 2.84 times higher risk of abnormal semen in the crude model (OR: 3.84; 95% CI: 1.64-8.95); such that remained after adjusting for several potential confounders. There was no significant association between dTAC or AHEI and the risk of abnormal semen in infertile men, either before or after adjusting for potential confounders. Total energy (p = 0.05), fat (p = 0.02), saturated fat (p = 0.02), mono-saturated fat (p = 0.009), Thiamine (Vitamin B1) (p = 0.02), Niacin (Vitamin B3) (p = 0.03), Calcium (p = 0.01), and Selenium (p = 0.01) were inversely associated with semen normality. Discussion The study suggests that certain dietary factors may affect semen quality, and the mechanisms underlying the observed associations are likely multifactorial, involving complex interactions between diet, oxidative stress, inflammation, and hormone levels. Further research is required to confirm the results, fully elucidate the mechanisms underlying the associations, and identify specific dietary interventions that may improve male fertility outcomes.

Abstract
The purpose of this article is to provide an explanation of the background behind a checklist that declares the laboratory methods used in a scientific study. It focuses primarily on implementing laboratory procedures to yield reliable results in basic semen examinations. While the World Health Organization (WHO) and international standards provide recommendations for basic semen examination, manuscripts submitted to Andrology frequently lack transparency regarding the specific techniques used. In addition, the terminology used for semen examination results often fails to provide a clear definition of the groups under study. Furthermore, the WHO's reference limits are often misinterpreted as strict boundaries between fertility and infertility. It is important to note that valid clinical andrological diagnoses and treatments cannot rely solely on semen examination results; they require proper laboratory procedures as a foundation for diagnosing and treating male patients. Therefore, scientific journals should promote the adoption of robust laboratory practices and an accurate definition of patient groups. A checklist can facilitate the design of high-quality studies and the creation of informative publications. Further, it can help journals assess submitted manuscripts and improve the overall quality of their publications.

Abstract
OBJECTIVE To identify patient factors associated with a clinically significant improvement in semen parameters among infertile men treated with the aromatase inhibitor anastrozole. DESIGN Multi-institutional retrospective cohort study. SETTING Two Tertiary Academic Medical Centers. PATIENTS A total of 90 infertile men treated at 2 tertiary academic medical centers who met inclusion criteria and obtained pretreatment and posttreatment semen analyses. INTERVENTION Prescription of anastrozole (median 3 mg/wk). MAIN OUTCOME MEASURES Upgrade in the World Health Organization sperm concentration category (WHO-SCC). Univariate logistic regression, multivariable logistic regression, and partitioning analyses were performed to identify statistically significant patient factors capable of predicting treatment response. RESULTS With anastrozole treatment, 46% (n = 41/90) of men responded favorably with a WHO-SCC upgrade, and 12% (n = 11/90) experienced a downgrade. Responders exhibited lower pretreatment levels of luteinizing hormone (LH, 4.7 vs. 8.3 IU/L) and follicle-stimulating hormone (4.7 vs. 6.7 IU/mL), higher pretreatment levels of testosterone (T, 356 vs. 265 ng/dL), and similar baseline level of estradiol (E2, 73% vs. 70% with detectible level). Baseline semen parameters differed, with anastrozole responders demonstrating higher baseline semen concentration (3.6 vs. 0.3 M/mL) and higher total motile sperm counts (3.7 vs. 0.1 M). Anastrozole therapy converted 29% (n = 26/90) of the cohort to normozoospermia and enabled intrauterine insemination access in 31% (n = 20/64) of previously ineligible patients. Interestingly, neither body mass index nor the baseline E2 level or E2-T ratio was associated with WHO-SCC upgrade. Multivariable logistic regression revealed the T-LH ratio (odds ratio: 1.02, 95% confidence interval: 1.00-1.03) and baseline nonazoospermia (odds ratio: 9.4, 95% confidence interval: 1.1-78.9) to be statistically significant predictors of WHO-SCC upgrade (area under receiver operating characteristic curve: 0.77). The final user-friendly partitioning model consisting of the T-LH ratio ≥100 and baseline non-azoospermia was 98% sensitive and 33% specific for WHO-SCC upgrades (area under the curve: 0.77). CONCLUSION Anastrozole therapy decreases serum E2 levels, increases serum gonadotropins, and clinically improves semen parameters in half of men with idiopathic infertility. Nonazoospermic infertile men with T-LH ratios ≥100 are likely to benefit from anastrozole treatment irrespective of baseline E2 level or E2-T ratio. Men with azoospermia rarely respond to anastrozole and should be counseled on alternative treatments.

Abstract
OBJECTIVE Seminal plasma cytokines are associated with fertility and reproductive health, but progressing their clinical utility is hampered by absence of reference data on concentration ranges of relevant cytokines in healthy men. We employed a systematic approach to assemble current evidence on the concentrations of immune regulatory cytokines present in seminal plasma (SP) of normozoospermic and/or fertile men and evaluated the impact of different platform methodologies for cytokine quantification. EVIDENCE REVIEW A systematic literature search was performed utilising PubMed, Web of Science and Scopus. Databases were searched from inception until 30th June 2022 inclusive, using combinations of keywords pertaining to seminal fluid and cytokines, and was restricted to human participants. Original data with values reported as concentration of specific cytokines in SP of men clearly defined as fertile or normozoospermic were extracted from studies written in English. RESULTS A total of 3769 publications were initially identified, of which 118 fulfilled the eligibility criteria for inclusion. A total of 51 individual cytokines are detectable in SP of healthy men. The number of studies reporting on each cytokine range from 1 to >20. The reported concentrations for many cytokines linked with fertility status, including IL6, CXCL8/IL8, and TNFA, are highly variable between published studies. This is associated with the different immunoassay methodologies utilised and may be exacerbated by a lack of validation of assays to ensure suitability for SP assessment. Due to the large variation between studies, accurate reference ranges for healthy men cannot be determined from the published data. CONCLUSIONS The concentrations of cytokines and chemokines detected in SP is inconsistent and highly variable between studies and cohorts, limiting current capacity to define reference ranges for cytokine concentrations in fertile men. The lack of standardisation in methods used to process and store SP, and variation in platforms used to evaluate cytokine abundance, are factors contributing to the observed heterogeneity. To progress the clinical utility of SP cytokine analysis will require standardisation and validation of methodologies so that reference ranges for healthy fertile men can be defined.

Abstract
Gamete and embryo quality are critical to the success rate of Assisted Reproductive Technology (ART) cycles, but there remains a lack of methods to accurately measure the quality of sperm, oocytes and embryos. The ability of Artificial Intelligence (AI) technology to analyze large amounts of data, especially video and images, is particularly useful in gamete and embryo assessment and selection. The well-trained model has fast calculation speed and high accuracy, which can help embryologists to perform more objective gamete and embryo selection. Various artificial intelligence models have been developed for gamete and embryo assessment, some of which exhibit good performance. In this review, we summarize the latest applications of AI technology in semen analysis, as well as selection for sperm, oocyte and embryo, and discuss the existing problems and development directions of artificial intelligence in this field.

Abstract
Introduction For laboratory tests, precision and accuracy are indispensable to ensure reliable results for both clinical diagnosis and research endeavors. The accuracy and reliability of results are important because they have an impact on both patient management and research. In this study, we evaluated the inter-observer variability between a trained technician and two academic residents, which acted both as a quality control measure as well as an assessment of training outcomes. Material and methods Freshly obtained semen samples from 28 subjects coming to the andrology laboratory were used. Semen analysis was performed by a regular technician permanently posted in the laboratory and two residents on completion of their posting in the andrology laboratory. All three examined the same sample after liquefaction for assessment of sperm motility, sperm concentration, sperm vitality, and sperm morphology. Semen analysis was done as per the recommendations of the WHO. Results The results of the study are presented as a coefficient of variation (CV), S charts, and Bland-Altman plot where we evaluated the interobserver variability in parameters on semen analysis of the same sample by three different assessors. The mean CV for sperm concentration across the samples was 6.24%. For sperm vitality, sperm morphology, and sperm motility the mean CV was 10.14%, 2.66%, and 8.11%, respectively. The S chart and Bland-Altman plot found a few random errors in measurements. Conclusion Regular quality control assessments are essential and should be implemented in andrology laboratories to ensure accurate and reliable results. Proper training of laboratory personnel is also vital for consistent outcomes. Other measures such as equipment calibration, use of high-quality reagents, and standard reporting are also crucial for the best results from a laboratory.

Abstract
BACKGROUNDS Despite a wide spectrum of contraceptive methods for women, the unintended pregnancy rate remains high (45% in the US), with 50% resulting in abortion. Currently, 20% of global contraceptive use is male-directed, with a wide variation among countries due to limited availability and lack of efficacy. Worldwide studies indicate that >50% of men would opt to use a reversible method, and 90% of women would rely on their partner to use a contraceptive. Additional reasons for novel male contraceptive methods to be available include the increased life expectancy, sharing the reproductive risks among partners, social issues, the lack of pharma industry involvement and the lack of opinion makers advocating for male contraception. AIM The present guidelines aim to review the status regarding male contraception, the current state of the art to support the clinical practice, recommend minimal requirements for new male contraceptive development and provide and grade updated, evidence-based recommendations from the European Society of Andrology (EAA) and the American Society of Andrology (ASA). METHODS An expert panel of academicians appointed by the EAA and the ASA generated a consensus guideline according to the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) system. RESULTS Sixty evidence-based and graded recommendations were produced on couple-centered communication, behaviors, barrier methods, semen analysis and contraceptive efficacy, physical agents, surgical methods, actions before initiating male contraception, hormonal methods, non-hormonal methods, vaccines, and social and ethical considerations. CONCLUSION As gender roles transform and gender equity is established in relationships, the male contribution to family planning must be facilitated. Efficient and safe male-directed methods must be evaluated and introduced into clinical practice, preferably reversible, either hormonal or non-hormonal. From a future perspective, identifying new hormonal combinations, suitable testicular targets, and emerging vas occlusion methods will produce novel molecules and products for male contraception.

Abstract
Objective Varicocele is considered the most common reversible cause of male infertility. However, some men do not clinically improve after surgical repair. We aimed to identify preoperative factors associated with decreased semen parameters and clinical "downgrading" of total motile sperm count (TMSC) following varicocelectomy. Methods We examined men with preoperative laboratory testing and pre- and postoperative semen analyses (SA) who underwent varicocelectomy between 2010 and 2020. Ejaculate volume, sperm motility, sperm concentration, TMSC, and clinical grade of TMSC (in vitro fertilization: <5M sperm, intrauterine insemination: 5-9M sperm, natural pregnancy: >9M sperm) were used to determine postoperative outcomes. Demographic and clinical factors were compared between cohorts. Results Among 101 men who underwent varicocelectomy, 35 (34.7%) had decreased postoperative TMSC with a median follow-up of 6.6 months (interquartile range 3.9-13.6 months). Eleven (10.9%) men experienced TMSC clinical "downgrading" following surgery. Clinical grade III varicocele was significantly associated with decreased sperm motility on postoperative SA (OR 4.1, 95% CI 1.7-10.0, p=0.002), and larger left testicle volume (OR 1.4, 95% CI 1.1-1.8, p=0.02) was associated with clinical "downgrading" after varicocelectomy. Conclusion A small but significant proportion of men experienced a "downgrading" of semen parameters after varicocelectomy. Larger left testis size was associated with clinical downgrading, whereas clinical grade III varicoceles were associated with lower post-treatment sperm motility. These data are critical for preoperative patient counseling.

Abstract
OBJECTIVE To understand how chronic exposure to industrial air pollution is associated with male fertility through semen parameters. DESIGN Retrospective cohort study. PATIENTS Men in the Subfertility, Health, and Assisted Reproduction cohort who underwent a semen analysis in the two largest healthcare systems in Utah from 2005-2017 with ≥1 measured semen parameter (N = 21,563). INTERVENTION(S) Residential histories for each man were constructed using locations from administrative records linked through the Utah Population Database. Industrial facilities with air emissions of nine endocrine-disrupting compound chemical classes were identified from the Environmental Protection Agency Risk-Screening Environmental Indicators microdata. Chemical levels were linked with residential histories for the 5 years before each semen analysis. MAIN OUTCOME MEASURES Semen analyses were classified as azoospermic or oligozoospermic (< 15 M/mL) using World Health Organization cutoffs for concentration. Bulk semen parameters such as concentration, total count, ejaculate volume, total motility, total motile count, and total progressive motile count were also measured. Multivariable regression models with robust standard errors were used to associate exposure quartiles for each of the nine chemical classes with each semen parameter, adjusting for age, race, and ethnicity, as well as neighborhood socioeconomic disadvantage. RESULTS After adjustment for demographic covariates, several chemical classes were associated with azoospermia and decreased total motility and volume. For exposure in the 4th relative to 1st quartile, significant associations were observed for acrylonitrile (βtotal motility = -0.87 pp), aromatic hydrocarbons (odds ratio [OR]azoospermia = 1.53; βvolume = -0.14 mL), dioxins (ORazoospermia = 1.31; βvolume = -0.09 mL; βtotal motility = -2.65 pp), heavy metals (βtotal motility = -2.78pp), organic solvents (ORazoospermia = 1.75; βvolume = -0.10 mL), organochlorines (ORazoospermia = 2.09; βvolume = -0.12 mL), phthalates (ORazoospermia = 1.44; βvolume = -0.09 mL; βtotal motility = -1.21 pp), and silver particles (ORazoospermia = 1.64; βvolume = -0.11 mL). All semen parameters significantly decreased with increasing socioeconomic disadvantage. Men who lived in the most disadvantaged areas had concentration, volume, and total motility of 6.70 M/mL, 0.13 mL, and 1.79 pp lower, respectively. Count, motile count, and total progressive motile count all decreased by 30-34 M. CONCLUSION(S) Several significant associations between chronic low-level environmental exposure to endocrine-disrupting compound air pollution from industrial sources and semen parameters were observed. The strongest associations were seen for increased odds of azoospermia and declines in total motility and volume. More research is needed to further explore additional social and exposure factors as well as expand on the risk posed to male reproductive health by the studied chemicals.

Abstract
The impact of ejaculatory abstinence on semen parameters using in-office semen analyses has been well-established; however, their variability has not been evaluated in men using mail-in semen analysis kits. Our study aims to describe how the sperm parameters using mail-in semen analysis tests change with abstinence and validate their equivalence to those seen with in-office semen analysis tests. We retrospectively reviewed the semen analysis results of men using mail-in semen analysis tests provided by Give Legacy, Inc (Legacy) facilities from 2019 to 2021. We collected their demographic information, abstinence duration, and semen parameters (conventional and kinematic) from their records. Semen samples were categorized as normozoospermic and oligozoospermic based on concentration. The shape of the relationship between abstinence duration and semen parameters was assessed via generalized additive models. We have collected 3,469 unique samples provided by 2,609 (75%) normozoospermic men and 860 (25%) oligozoospermic from all over the United States. In normozoospermic men, longer periods of sexual abstinence were linked to higher levels of sperm concentration, total sperm count, and total motile sperm. However, there was a decline in both total and progressive motility. Conversely, in oligozoospermic men, extended periods of abstinence led to a rapid decline in total motile sperm, as well as total and progressive motility. There was no significant correlation observed between sexual abstinence and variations in sperm morphology. Our study shows that variability of sperm parameters with abstinence, as measured through mail-in semen analysis tests, is comparable to the patterns observed with conventional in-office sperm testing.

Abstract
Background Air pollution may impair male fertility, but it remains controversial whether air pollution affects semen quality until now. Objectives We undertake a meta-analysis to explore potential impacts of six pollutants exposure during the entire window (0-90 days prior to ejaculation) and critical windows (0-9, 10-14, and 70-90 days prior to ejaculation) on semen quality. Methods Seven databases were retrieved for original studies on the effects of six pollutants exposure for 90 days prior to ejaculation on semen quality. The search process does not limit the language and search date. We only included original studies that reported regression coefficients (β) with 95% confidence intervals (CIs). The β and 95% CIs were pooled using the DerSimonian-Laird random effect models. Results PM2.5 exposure was related with decreased total sperm number (10-14 lag days) and total motility (10-14, 70-90, and 0-90 lag days). PM10 exposure was related with reduced total sperm number (70-90 and 0-90 lag days) and total motility (0-90 lag days). NO2 exposure was related with reduced total sperm number (70-90 and 0-90 lag days). SO2 exposure was related with declined total motility (0-9, 10-14, 0-90 lag days) and total sperm number (0-90 lag days). Conclusion Air pollution affects semen quality making it necessary to limit exposure to air pollution for Chinese men. When implementing protective measures, it is necessary to consider the key period of sperm development.

Abstract
OBJECTIVES This study aimed to determine the relationship between oxidative stress (OS) measured by the oxidation-reduction potential (ORP) and the results of semen analysis among men from infertile couples. METHODS This cross-sectional study included 166 men from infertile couples, determined according to the World Health Organization guidelines. The general characteristics, semen analysis, sperm chromatin dispersion assay, and ORP of all subjects were evaluated and analyzed statistically. RESULTS Among 166 men from infertile couples, individuals with OS had a significantly higher DNA fragmentation index (DFI) than men without OS (22.37% ± 11.67% vs. 17.98% ± 8.98%). The sperm concentration, total sperm count, motility rate, and normal morphology were negatively correlated, while and an abnormal head and neck-tail were positively correlated with ORP. There was also a positive association between the DFI and OS level. The optimal ORP threshold for determining sperm quality was 0.77 mV/106 sperm/mL (sensitivity, 50.4%; specificity, 93.5%; positive predictive value, 52.9%; negative predictive value, 32.3%). CONCLUSIONS Determining the ORP suggests that OS has an adverse effect on the total sperm count, sperm motility, sperm concentration, morphology, vitality, and DNA fragmentation index.

Abstract
INTRODUCTION Oxidative stress is known as a mechanism underlying male infertility; it is defined as an imbalance between pro-oxidants and antioxidants leading to DNA damage, peroxidation of plasma membrane lipids, and protein oxidation. This study was conducted to investigate the relationship between total antioxidant capacity and sperm parameters in male infertility. METHODS A total of 187 men with infertility (asthenospermia group (n=51), oligospermia group (n=40), and control group (n=96) were included in the current study. The following risk factors were recorded: age, sperm volume, sperm motility, hormone levels, and dietary antioxidant content. RESULTS Demographic parameters and hormone levels of cases showed no statistically significant difference between groups (p > 0.05). Semen volume, motility, vitamin A, retinol, vitamin D, and vitamin C levels were statistically significantly lower in the asthenospermia and oligospermia groups (p < 0.05). According to the logistic regression model, lower vitamin A, retinol, vitamin D, and vitamin C levels were risk factors for poor sperm outcomes (p < 0.001). Conclusıon: Male infertility with poor sperm outcomes should have an assessment of antioxidant capacity and nutritional specialization including food high in antioxidants could improve sperm parameters in asthenospermia and oligospermia and it could be used for therapeutic opportunities.

Abstract
INTRODUCTION Male infertility contributes to a significant proportion of infertility cases, and advanced paternal age has been suggested to affect semen quality and fertility. However, the relationship between age and semen quality remains inconclusive, with conflicting findings reported in the literature. This study aimed to investigate the effect of age on semen quality among male partners of infertile couples in a tertiary care center in eastern India. METHODS A cross-sectional observational study was conducted, involving 390 male participants aged 21-50 years, who were referred to the andrology laboratory for semen analysis between January 2019 and December 2022. Participants were categorized into three age groups (21-30, 31-40, and 41-50 years). Semen parameters, including sperm concentration, semen volume, motility, and morphology, were assessed according to the World Health Organization guidelines. RESULTS Among the participants, no significant differences were observed in semen volume, motility, and morphology across different age groups. However, a statistically significant difference in sperm concentration among the three age groups was observed (p = 0.022). Spearman correlation analysis revealed a positive correlation between age and sperm concentration (r = 0.124, p = 0.013) as well as total sperm count (r = 0.10, p = 0.049). CONCLUSION In this study, no significant decline in semen quality with age was found among male partners of infertile couples aged 21-50 years. These findings highlight the complex relationship between age and semen quality and emphasize the need for further research to better understand the underlying mechanisms and provide more conclusive evidence regarding the impact of age on male fertility.

Abstract
(1) Background: While females start their gynecological examinations during puberty, only few men decide to be visited by urologists in their youth. Given the participation in the EcoFoodFertility research project, our department had the opportunity to screen young males that were supposedly healthy. (2) Results: from January 2019 to July 2020, we evaluated 157 patients with sperm, blood analysis, and uroandrological examinations. The inclusion criteria were age 18-40 and absence of previous urological disease (urology-naïve). The primary endpoint of the study was to record uroandrological diseases that are occasionally discovered during examination in asymptomatic young men. The average age was 26.9 years (range 18-40); average testicular volume was 15.7 mL (range 12-22 mL); and 45.2% reported abnormal semen analysis: 62 cases of teratozoospermia, 27 asthenozoospermia, 18 oligozoospermia, and 2 azoospermia were discovered respectively; 4/157 patients were diagnosed with hypogonadism; 2 cases with suspicious testicular mass resulted in testicular cancer; and 31 suspected varicoceles and 8 patients with mild sexual dysfunctions were managed. (3) Conclusions: an uroandrological evaluation of young asymptomatic males allowed for the prompt diagnosis of different urological conditions, including cancerous ones, in our series. Despite being debatable, combining urological counselling with physical examination, semen analysis, and a laboratory profile could be useful and cost-effective in order to ameliorate male health.

Abstract
This study aimed to determine whether an analysis of stallion ejaculate could accurately predict the likelihood of pregnancy resulting from artificial insemination in mares. This study involved 46 inseminations of 41 mares, using 7 standardbred stallions over a 5-week period at an Australian pacing stud. Semen quality was assessed immediately after collection and again after chilling at ~5 °C for 24 h. The assessment involved evaluating ejaculate volume, sperm concentration, and motility parameters using an iSperm® Equine portable device. After the initial evaluation, a subpopulation of cells was subjected to a migration assay through a 5 µm polycarbonate filter within a Samson™ isolation chamber over a 15 min period. The cells were assessed for their concentration, motility parameters, and ability to reduce the membrane impermeant tetrazolium salt WST-1. The data, combined with the stallion and mare's ages, were used to predict the likelihood of pregnancy, as confirmed by rectal ultrasound sonography performed 14 days post ovulation. The criteria used to predict pregnancy were optimized for each individual stallion, resulting in an overall accuracy of 87.9% if analyzed pre-chilling and 95% if analyzed post-chilling. This study suggests that an analysis of stallion ejaculate can be used to predict the likelihood of pregnancy resulting from artificial insemination in mares with a high level of accuracy.

Abstract
Male and female infertility has become a worldwide public health problem. The global obesity epidemic has paralleled a decrease in semen quality. Yet, the association between body mass index (BMI) and sperm parameters remains controversial. The objective of this study is to determine the link between body mass index and seminal parameters. We made an observational study and retrospective analysis. Men who made semen analysis during the period of January 2015 to September 2021 in Reims University Hospital, were included. A total of 1 655 patients were recruited and separated into five groups according to BMI values. Second- and third-degree obesity had a significantly higher risk of having a pathological sperm count (p: 0,0038). Second- and Third-degree obesity was associated with a pathologic vitality (p: 0,012). No significant differences existed between sperm mobility and body mass index. Regarding low body mass index, a significant difference exists on the sperm morphology (p: 0,013). Sperm morphology is also impacted in overweight and obesity groups. The information of the couples on weight is necessary to improve sperm parameters, spontaneous pregnancies and efficacity of assisted reproductive technic.

Abstract
Approximately 31% of patients with 22q11.2 deletion syndrome (22q11.2DS) have genitourinary system disorders and 6% of them have undescended testes. Haploinsufficiency of genes on chromosome 22q11.2 might contribute to the risk of 22q11.2DS. In this study, we used mice with single-allele deletion in mitochondrial ribosomal protein L40 (Mrpl40 +/- ) as models to investigate the function of Mrpl40 in testes and spermatozoa development. The penetrance of cryptorchidism in Mrpl40 +/- mice was found to be higher than that in wild-type (WT) counterparts. Although the weight of testes was not significantly different between the WT and Mrpl40 +/- mice, the structure of seminiferous tubules and mitochondrial morphology was altered in the Mrpl40 +/- mice. Moreover, the concentration and motility of spermatozoa were significantly decreased in the Mrpl40 +/- mice. In addition, data-independent acquisition mass spectrometry indicated that the expression of genes associated with male infertility was altered in Mrpl40 +/- testes. Our study demonstrated the important role of Mrpl40 in testicular structure and spermatozoa motility and count. These findings suggest that Mrpl40 is potentially a novel therapeutic target for cryptorchidism and decreased motility and count of spermatozoa.

Abstract
The effects of the coronavirus disease 2019 (COVID-19) pandemic on male fertility have received considerable attention because human testes contain high levels of angiotensin-converting enzyme-2 receptors, through which severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can enter. Early studies showed decreases in semen quality during and after recovery from COVID-19. However, no semen quality studies have examined the effects of widespread subclinical and mild disease, as well as changes in lifestyle, psychosocial behavior, intake of dietary supplements, and stress. This cross-sectional study compared semen quality parameters in male partners of infertile couples between men who underwent semen analysis before the COVID-19 pandemic (prepandemic group) and men who underwent semen analysis during the pandemic period (pandemic group); the analysis sought to clarify the overall effects of the pandemic. No participants in the pandemic group had experienced clinically overt disease. Among the 239 participants, mean body weight (P = 0.001), mean body mass index (P < 0.001), median sperm concentration (P = 0.014), total sperm count (P = 0.006), and total percentages of motile (P = 0.013) and abnormal cells (P < 0.001) were significantly greater in the pandemic group (n = 137) than those in the prepandemic group (n = 102). Among abnormal cells, the percentages of cells with excess residual cytoplasm (P < 0.001), head defects (P < 0.001), and tail defects (P = 0.015) were significantly greater in the pandemic group than those in the prepandemic group. With the exception of morphology, the overall semenogram results were better in the pandemic group than those in the prepandemic group.

Abstract
BACKGROUND Numerous studies have reported declines in semen quality and other markers of male reproductive health. Our previous meta-analysis reported a significant decrease in sperm concentration (SC) and total sperm count (TSC) among men from North America-Europe-Australia (NEA) based on studies published during 1981-2013. At that time, there were too few studies with data from South/Central America-Asia-Africa (SAA) to reliably estimate trends among men from these continents. OBJECTIVE AND RATIONALE The aim of this study was to examine trends in sperm count among men from all continents. The broader implications of a global decline in sperm count, the knowledge gaps left unfilled by our prior analysis and the controversies surrounding this issue warranted an up-to-date meta-analysis. SEARCH METHODS We searched PubMed/MEDLINE and EMBASE to identify studies of human SC and TSC published during 2014-2019. After review of 2936 abstracts and 868 full articles, 44 estimates of SC and TSC from 38 studies met the protocol criteria. Data were extracted on semen parameters (SC, TSC, semen volume), collection year and covariates. Combining these new data with data from our previous meta-analysis, the current meta-analysis includes results from 223 studies, yielding 288 estimates based on semen samples collected 1973-2018. Slopes of SC and TSC were estimated as functions of sample collection year using simple linear regression as well as weighted meta-regression. The latter models were adjusted for predetermined covariates and examined for modification by fertility status (unselected by fertility versus fertile), and by two groups of continents: NEA and SAA. These analyses were repeated for data collected post-2000. Multiple sensitivity analyses were conducted to examine assumptions, including linearity. OUTCOMES Overall, SC declined appreciably between 1973 and 2018 (slope in the simple linear model: -0.87 million/ml/year, 95% CI: -0.89 to -0.86; P < 0.001). In an adjusted meta-regression model, which included two interaction terms [time × fertility group (P = 0.012) and time × continents (P = 0.058)], declines were seen among unselected men from NEA (-1.27; -1.78 to -0.77; P < 0.001) and unselected men from SAA (-0.65; -1.29 to -0.01; P = 0.045) and fertile men from NEA (-0.50; -1.00 to -0.01; P = 0.046). Among unselected men from all continents, the mean SC declined by 51.6% between 1973 and 2018 (-1.17: -1.66 to -0.68; P < 0.001). The slope for SC among unselected men was steeper in a model restricted to post-2000 data (-1.73: -3.23 to -0.24; P = 0.024) and the percent decline per year doubled, increasing from 1.16% post-1972 to 2.64% post-2000. Results were similar for TSC, with a 62.3% overall decline among unselected men (-4.70 million/year; -6.56 to -2.83; P < 0.001) in the adjusted meta-regression model. All results changed only minimally in multiple sensitivity analyses. WIDER IMPLICATIONS This analysis is the first to report a decline in sperm count among unselected men from South/Central America-Asia-Africa, in contrast to our previous meta-analysis that was underpowered to examine those continents. Furthermore, data suggest that this world-wide decline is continuing in the 21st century at an accelerated pace. Research on the causes of this continuing decline and actions to prevent further disruption of male reproductive health are urgently needed.

Abstract
The purpose of this study is to investigate the optimal framerate (FR) and the use of different counting chambers for improving CASA-Mot technology use in Andrology. Images were captured at 500 fps, then segmented and analyzed in several ranges of FRs (from 25 to 250) to define the asymptotic point that as an optimal FR. This work was replicated using counting chambers based in capillarity (disposable) or drop displacement (reusable) to study their effects on the motility results and kinematic values of the samples under the different experimental conditions. The α value (asymptote corresponding to FRo) of the exponential curve was 150.23 fps, corresponding to a VCL of 130.58 mm/s, far from the value of 98.89 mm/s corresponding to 50 fps (the highest FR used by most current CASA-Mot systems). Our results have shown that, when using reusable counting chambers, type and depth have influence. In addition, different results were obtained depending on the area of image captured inside the different counting chamber types. To have reliable results in human sperm kinematic studies, almost 150 fps should be used for capturing and analyzing and differences between chambers should be considered by sampling from different areas, to obtain a representative value of the whole sample.

Abstract
Reciprocal translocation (RT) carriers produce a proportion of unbalanced gametes that expose them to a higher risk of infertility, recurrent miscarriage, and fetus or children with congenital anomalies and developmental delay. To reduce these risks, RT carriers can benefit from prenatal diagnosis (PND) or preimplantation genetic diagnosis (PGD). Sperm fluorescence in situ hybridization (spermFISH) has been used for decades to investigate the sperm meiotic segregation of RT carriers, but a recent report indicates a very low correlation between spermFISH and PGD outcomes, raising the question of the usefulness of spermFISH for these patients. To address this point, we report here the meiotic segregation of 41 RT carriers, the largest cohort reported to date, and conduct a review of the literature to investigate global segregation rates and look for factors that may or may not influence them. We confirm that the involvement of acrocentric chromosomes in the translocation leads to more unbalanced gamete proportions, in contrast to sperm parameters or patient age. In view of the dispersion of balanced sperm rates, we conclude that routine implementation of spermFISH is not beneficial for RT carriers.

Abstract
STUDY QUESTION Is prior testicular torsion associated with testicular function (semen quality and reproductive hormones) in young men from the general population? SUMMARY ANSWER In young men from the general population, no differences in semen parameters were observed in those who had experienced testicular torsion compared to controls and observations of higher FSH and lower inhibin B were subtle. WHAT IS KNOWN ALREADY Testicular function may be impaired after testicular torsion, but knowledge is sparse and based on studies with small sample sizes and no control group or a less than ideal control group. STUDY DESIGN, SIZE, DURATION A cross-sectional population-based study was carried out including 7876 young Danish men with unknown fertility potential, examined from 1996 to 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS All men (median age 19.0 years) had a physical examination, provided a blood and semen sample, and filled in a questionnaire including information about prior testicular torsion, birth, lifestyle and current and previous diseases. Markers of testicular function, including testis volume, semen parameters and reproductive hormones, were compared between men operated for testicular torsion and controls, using multiple linear regression analyses. MAIN RESULTS AND THE ROLE OF CHANCE The average participation rate was 24% for the entire study period. In total, 57 men (0.72%) were previously operated for testicular torsion (median age at surgery 13.4 years) of which five had only one remaining testicle. Men with prior testicular torsion were more often born preterm (25% versus 9.5% among controls), and they had significantly higher FSH and lower inhibin B levels, and a lower inhibin B/FSH ratio than controls in crude and adjusted models. The association was mainly driven by the subgroup of men who had undergone unilateral orchiectomy. No differences in semen parameters were observed. LIMITATIONS, REASONS FOR CAUTION A limitation is the retrospective self-reported information on testicular torsion. Also, results should be interpreted with caution owing to the high uncertainty of the observed differences. WIDER IMPLICATIONS OF THE FINDINGS Overall, the results of our study are reassuring for men who have experienced testicular torsion, especially when treated with orchiopexy, for whom reproductive hormone alterations were subtle and without obvious clinical relevance. Our study found no differences in semen parameters, but follow-up studies are needed to assess any long-term consequences for fertility.

Abstract
OBJECTIVE During the COVID-19 era, semen collection at infertility centers might increase the risk of spreading SARS-CoV-2. Seminal fluid collection at home is an alternative method for preventing this spread. However, there is no conclusion about the effect of home vs clinic semen collection on semen parameters and assisted reproductive technology outcomes. This systematic review and metaanalysis aimed to assess the effect of semen collection location on semen parameters and fertility outcomes. DATA SOURCES A literature search was conducted using the major electronic databases including MEDLINE via Ovid, EMBASE, Scopus, CINAHL, OpenGrey, and CENTRAL from their inception to September 2021. CLINICALTRIALS gov was searched to identify the ongoing registered clinical trials. STUDY ELIGIBILITY CRITERIA We included all human randomized controlled trials and observational studies that investigated the effect of at-home semen collection vs in-clinic semen collection on semen parameters and fertility outcomes. METHODS We pooled the mean difference and risk ratio using Review Manager software version 5.4.1 (The Cochrane Collaboration, 2022). The Grading of Recommendations, Assessment, Development and Evaluations approach was applied to assess the quality of evidence. RESULTS Seven studies (3018 semen samples) were included. Overall, at-home semen collection results made little to no difference in semen volume (mean difference, 0.37; 95% confidence interval, -0.10 to 0.85; low-quality evidence), sperm count (mean difference, -6.02; 95% confidence interval, -27.26 to 15.22; very low-quality evidence), and sperm motility (mean difference, 0.76; 95% confidence interval, -4.39 to 5.92; very low-quality evidence) compared with in-clinic semen collection. There was no difference in fertilization rate (risk ratio, 1.00; 95% confidence interval, 0.97-1.03; very low-quality evidence) and pregnancy rate in in vitro fertilization (risk ratio, 1.04; 95% confidence interval, 0.86-1.25; very low-quality evidence). CONCLUSION At-home semen collection had no adverse effects on semen parameters or fertility outcomes compared with in-clinic collection. However, higher-quality evidence is needed.

Abstract
Background The male reproductive system may be a potential target for SARS-CoV-2 since the presence of ACE and TMPRS2 receptors. After a first report of the presence of SARS-CoV-2 in semen of COVID-19 patients, several papers reported that SARS-CoV-2 was not detected in the semen. However, some evidences indicated that COVID-19 disease could impair semen parameters. During the infection, or in a short period after, a reduction in sperm concentration and motility and an increase in DNA fragmentation were observed, even in asymptomatic patients. There is no conclusive data exploring whether this damage changes with time. We investigated whether COVID-19 disease has a negative impact on semen parameters and male reproductive potential after recovery. Methods In this longitudinal retrospective study, we enrolled 20 men who had COVID-19 disease. We compared sperm parameters in samples collected before COVID-19 and after infection (8.3 ± 4.8 months). We also evaluated the reproductive potential in pre- and post-COVID-19 infertility treatments of 8 self-controlled couples as well as in 40 cycles after COVID-19 infection of the male partner. Results For most patients, we obtained results of more than one semen analysis before and after COVID-19. After adjusting for age, days of sexual abstinence, frequency of ejaculations and presence of fever, we found no significant difference over time in any semen parameter. The interval between COVID-19 infection and subsequent infertility treatments was 10.7 ± 7.5 months. There were no differences in the embryological and clinical outcomes of infertility treatments performed before and after male infection. One couple obtained a single pregnancy in the post COVID-19 IUI. Normal fertilization (65%), cleavage (99%) and blastocyst development (40%) rates in treatments performed after male infection were within the expected range of competencies. A total of 5 singleton and 1 twin clinical pregnancies were obtained, and 6 healthy children were born. A total of 10 blastocysts have been cryopreserved. Conclusion Our data are reassuring that COVID-19 disease has no negative effect on semen quality and male reproductive potential when semen samples are collected three months or more after infection.

Abstract
Due to their major medical importance in Latin America, lancehead pitvipers are frequently kept and bred in captivity for venom extraction to the production of antivenom serums. Nevertheless, despite the great contribution given to captive breeding, much of the knowledge of Bothrops' reproductive biology derived from sporadic and insufficient data provided by zoological collections. Thus, we aimed to investigate seasonal changes in gonadosomatic index (GSI) and seminal parameters (e.g., volume, concentration, motility, viability, and acrosome integrity) of five species of lancehead pitvipers from different biomes and phylogenetic groups, maintained in the indoors serpentarium at Butantan Institute (Brazil). Patterns of variation in GSI and semen parameters differed from one species to another, suggesting that captive populations should perhaps be managed distinctly to maximize reproductive success. Furthermore, in none of the studied species did changes in GSI occur concomitantly with seminal variations. GSI remained unaltered year-round for Jararaca (Bothrops jararaca) and Brazilian lancehead (Bothrops moojeni), whereas it peaked in the autumn for Common lancehead (Bothrops atrox), Jararacussu (Bothrops jararacussu), and Whitetail lancehead (Bothrops leucurus). But surprisingly, the scenario was inverted when we estimated the total number of motile spermatozoa per season, as Jararaca and Brazilian lancehead displayed seasonal differences and the other species did not vary throughout the year. Potential ecological and evolutionary factors underlying these differences were also discussed in the present article. Together, these findings can help to better define breeding management strategies for each species in captivity, in addition to optimizing the future use of artificial insemination and semen cryopreservation.

Preoperative Predictors for the Presence of Motile Spermatozoa in the Epididymis and Patency of Anastomosis during Microsurgical Vasoepididymal Anastomosis in Patients with Obstructive Azoospermia.

Abstract
Background Following microsurgical vaso-epididymal anastomosis (VEA), anastomotic patency with sperm returning to the ejaculate is not always present and may even be delayed. The presence of motile spermatozoa is highly suggestive of future patency following surgery. Aims We prospectively analyse the factors that could predict motile spermatozoa at the epididymis intraoperatively and predictors of patency in patients with obstructive azoospermia (OA) undergoing microsurgical VEA. Settings and Design Department of Urology of a tertiary care centre in Northern India. It is a prospective observational study. Materials and Methods Over a 2-year period (July 2019 to June 2021), 26 patients with idiopathic OA were enrolled in the study. Twenty patients underwent microsurgical VEA. Patients were divided into two groups based on the presence/absence of intraoperative motile spermatozoa. Statistical Analysis Used Analysis of preoperative and intraoperative factors was done using the Mann-Whitney U-test, Chi-squared test and Fischer exact test. Results Out of 20 patients, 5 (group 2) had intraoperative motile spermatozoa in the epididymal fluid and 15 (group 1) had nonmotile spermatozoa. Low luteinising hormone (LH) levels (P = 0.01) and high testosterone levels (P = 0.05) were the predictive of presence of motile spermatozoa in epididymal fluid. Mean follow-up was 9 months (6-18 months). Predictors of higher patency were grade 2 epididymis (firm, turgid and tense) (P = 0.003), low LH levels (P = 0.03), low sertoli cell index (P = 0.006), high sperm-Sertoli index (P = 0.002) and better surgeon satisfaction (P = 0.01). Conclusion Low LH levels and high testosterone levels may be predictive of the presence of motile spermatozoa in epididymal fluid. Firm, turgid and tense epididymis, low Sertoli cell index, high sperm-Sertoli index and surgeon satisfaction suggest a greater chance of success after VEA for idiopathic azoospermia.
